i'll just find some 2.85's then, better to do it correctley now than have to change it again further down the line

This is a good price for them : http://www.aliexpress.com/item/Ams1117-2-85-2-85v-1a-power-supply-voltage-stabilizing/771958640.html

I can't seem to find any uk suppliers that do them for a decent price, so it looks like getting them from china is my only choice
